how does light intensity affect the rate of photosynthesis?

Repeat the process but this time place the cup of disks in a heated beaker of water and put a thermometer in the cup of disks to record temperature.

how does temperature affect the rate of photosynthesis?

how does the concentration of carbon dioxide affect the rate of photosynthesis?

Effects of high temperature on photosynthesis and …

Using a water temperature sensor over a period of time allows the user to gain an understanding of these variations in water temperature, and of what is normal for each specific sample site.

Temperature response of photosynthesis and its …


Discuss lab results with students. How might photosynthesis and aquatic respiration affect water chemistry in a lake environment? Consider how photosynthesis and respiration might affect oxygen concentrations, temperature, and pH in a lake.

Students are challenged to demonstrate that photosynthesis and respiration occur in lakes. They begin by attempting to demonstrate that photosynthesis and respiration can be measured in lab microcosms. Students need to choose a water quality measure(s) to analyze in laboratory microcosms. They should begin by researching the effects that respiration can have on water temperature, pH, CO2, and DO, using the "Understanding" portion of the WOW website. They should choose a measure(s) that they feel correlates strongly to photosynthesis and . Students should write a procedural plan for testing their hypothesis.

photosynthesis notes - Biology Junction

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

When temperatures rise too far above the optimum temperature, the enzymes controlling the reaction denature and can no-longer catalyse the reactions; photosynthesis ceases.

Photosynthesis responses to light and temperature - …

Because we need the experiment to be a fair
one and we know from our research that temperature can affect the rate
of photosynthesis we needed to cut down the heat transferring from the
light to our experiment as much as we can.

temperature and air humidity, for example

Above the maximum carbon dioxide concentration, further increases in carbon dioxide concentration have no further effect on the photosynthesis rate (because either the light-absorbing pigments are saturated and /or the carbon dioxide which is saturating the chloroplasts is limiting the Calvin cycle and/or the temperature is too low).
Because these three factors combine to determine the rate of photosynthesis, maximum rates of photosynthesis can alter if one of the other factors changes.
The rate of photosynthesis is typically measured as the amount of oxygen produced or the amount of carbon dioxide consumed in a given time.
Other environmental factors that can influence photosynthesis are the following.
